One Exchange Install, Multiple OWAs
I've setup Exchange 2007 all on one box and its now accepting mail for two (primary)companyB.comOWA works for with a certificate warning. I'm about ot purchase a certificate for it, but I'd also like to setup as well. Since SSLs are tied to a URL, I can't simply point that record to the primary OWA URL. Anyone have any suggestions?Pirooz Javan

Dear Pirooz, From your post, I understand that you have two domain names, and you want to purchase a SSL certificate to support both domain names. Based on my research, we can achieve that by perform the following steps: To configure your SSL certificates to use multiple Client Access server host names, do the following steps: 1. Use the New-ExchangeCertificate cmdlet to create a certificate request file. You should include all the domain names after domainname parameter. New-ExchangeCertificate -generaterequest -subjectname "dc=com,dc=contoso,o=Contoso Corporation," -domainname, CAS01,, -PrivateKeyExportable $true -path c:\certrequest_cas01.txt 2. Send this file to a Windows Certificate Services certification authority and use the Web server template on the Certification Authority page. This will result in a .cer file that can be imported to the Client Access server. Import-ExchangeCertificate -path <certificate_file_name>.cer -friendlyname "Contoso CAS01" 3. Use the Get-ExchangeCertificate cmdlet to determine the thumbprint for your certificate. Get-ExchangeCertificate -DomainName "CAS01" 4. After you have imported the certificate, you can assign it to IIS, IMAP4, and POP3 by using the Enable-ExchangeCertificate cmdlet. Enable-ExchangeCertificate -thumbprint <certificate-thumbprint> -services "IIS,POP,IMAP" For more information How to Configure SSL Certificates to Use Multiple Client Access Server Host Names, please look through the following article: How to Configure SSL Certificates to Use Multiple Client Access Server Host Names If anything is unclear, dont hesitate to ask me.
